Detailed Description

Cache source images for strips.

• Keyed by (strip + frame index within strip media + view ID).
• Caching is only done for strips that are independent of any other strips (images, movies, no-input effect strips like Text and Color).
• When full, cache eviction policy is to remove frames furthest from the current-frame, biasing towards removal of frames behind the current-frame.
• Invalidated fairly rarely, since the cached items only change when the source content changes.
